I’m trying to figure this out right now too. I ordered something like the valve extensions to try to make the valve for the outer tire curve back outside so it’s accessible. But it seems crazy to me that they build these dual tire vehicles like this and leave the driver struggling to figure out how to fill or check the air on these tires.
